These days, I would think they would recommend vaping over smoking. Vaping is apparently much safer, and only contains nicotine (plus glycerin/glycols). In my experience, cigarettes are much more relaxing and calming than vapes. I would think that the other compounds in cigarettes add to the overall soothing effect. Something about pure nicotine doses like through vapes just doesn't feel as good as a cigarette. One of my friends with cancer said the same thing about THC pills compared to smoking marijuana...
